A spherical steel ball bearing has a diameter of 2.540 cm at 26.00°C. (Assume the coefficient of linear expansion of the steel is 1.10 10-5(°C?1), and the average volume expansion coefficient is 3.30 10-5(°C?1).)
(a) What is its diameter when its temperature is raised to 99.0°C? (Give your answer to four significant figures.) cm
(b) What temperature change is required to increase its volume by 1.100%? °C
